Has anyone thought of deploying seismic survey vessels of the type that are used to do 3D and 4D surveys for subsea oil reservoirs, to locate the missing Malaysia Airlines jet (assuming it is under the sea, which seems to be a significant assumption this point)? I am not well-versed in the scientific aspects of seismic surveying -- perhaps someone with relevant expertise could fill us in on the technical feasibility of this?
